            Bug ID: 366488
           Summary: Too many sftp.so processes, not closing
           Product: kio-extras
           Version: unspecified
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: NOR
         Component: default
          Assignee: plasma-devel at kde.org
          Reporter: chalkerx at gmail.com

It looks like something constantly spawns new sftp.so processes without killing
the old ones.

Atm, I have 110 running sftp.so processes totalling to over 1 GiB RSS. I'm sure
I don't have that many sftp directories open.

Reproducible: Always

Steps to Reproduce:
0. Kill all Dolphin and sftp.so instances (or just make sure those are not
running) 
1. Open Dolphin
2. Open something over sftp:// protocol.
3. Wait about a minute.
4. Navigate to another, local directory
5. Open something else over sftp:// protocol in the same tab
6. Wait about a minute.
7. Open a new tab poiting to a local directory and close the first tab


Actual Results:  
1. There are 0 sftp.so processes running, totalling in 0 MiB.
2. There are 4 sftp.so processes running, totalling in 16 MiB.
3. There are 5 sftp.so processes running, totalling in 20 MiB.
4. There are 5 sftp.so processes running, totalling in 20 MiB.
5. There are 8 sftp.so processes running, totalling in 32 MiB.
6. There are 10 sftp.so processes running, totalling in 40 MiB.
7. There are 10 sftp.so processes running, totalling in 40 MiB.

Expected Results:  
I expect sftp.so old processes to be killed after a certain amount of time if
they couldn't be reused.

Some of the sftp.so processes present are over a month old.
